Coherent launches CW DFB lasers for silicon photonics transceivers

Coherent launched new high-efficiency continuous wave (CW) distributed feedback (DFB) lasers. Specifically engineered for silicon photonics transceiver modules, this innovative laser family represents a leap forward in indium phosphide (InP) laser technology. Designed to operate in the O-band (1310 nm region), the Coherent CW InP lasers redefine the capabilities of silicon photonics modulators used in 800G and 1.6T optical transceivers. These transceivers are on the forward edge of data transmission technology, crucially addressing the explosive bandwidth demands brought on by the rapid adoption of machine learning networks within AI-driven data centers. Unparalleled Power Efficiency for a New Era of Connectivity Featuring a proprietary low series-resistance design, the Coherent CW lasers achieve approximately 15% greater power efficiency compared with the current industry standard. This breakthrough addresses the critical demand for reduced power consumption in silicon photonics transceivers, providing customers with a clear edge in operational efficiency. “Our new family of CW lasers for silicon photonics is creating a wave of excitement among industry leaders,” said Dr. Kou-Wei Wang, Vice President of InP Directly Modulated Lasers & Photodiodes. “By lowering power consumption, we’re addressing one of the most pressing challenges faced by our customers today.
